This study aims to develop a low-cost, marker-free intelligent wound assessment system that can analyze wound photos taken with a standard smartphone. By comparing wound images over time, the system will generate a quantifiable Wound Progression Index (WPI) to provide objective feedback on whether a wound is improving, stable, or worsening. The long-term goal is to support early detection of wound deterioration and improve wound care in both clinical and home settings.
Participants receiving routine wound care will undergo standardized wound photography during dressing changes. Longitudinal wound images will be analyzed to develop and validate a marker-free wound progression assessment method. No treatment assignment or modification of standard clinical care will occur.

Agreement between marker-free and marker-based wound progression indices
To evaluate the agreement between the Marker-Free Wound Progression Index (WPI\_MF) and the gold-standard marker-based Wound Progression Index (WPI\_GS) derived from longitudinal wound photographs.
Time frame: Up to 6 months
Minimum image overlap threshold for reliable analysis
To determine the minimum overlap ratio required to achieve statistically acceptable agreement.
Time frame: Up to 6 months
